6
|
- Frequent
- In relation with patient activity, demand and need
|
|
7
|
- Radiocarpal and midcarpal joints make a bloc
- Ligaments avoid dislocation both ulnarly and anteriorly
- In RA carpus tend to slide ulnarly and anteriorly
|
|
8
|
- Ulnar head is immobile
- Weight bearing part of the wrist
- Radius and carpus attached by ulno-triquetral ligament
- In RA by ligament distention or bone erosion
- Radius/carpus dislocated anteriorly
- Prominence of the ulnar head and Manu Supinata
|

- Low vs high patient demand
- Resection only when necessary
- Minimal resection
- Stabilization
